FAIRVIEW - Fairview police are asking for the public's help in locating Matthew David Wicker, a homeless man wanted on assault and robbery charges.

Police say Wicker, 39, was identified as a suspect during the investigation of a Sept. 9 attack in the Salish Ponds area. A homeless man who was camping was confronted by two people, severely beaten with a baseball bat and lost consciousness, police say.

The victim, upon regaining consciousness the next morning, walked to the Target store in Fairview, collapsed in the parking lot and was transported to Legacy Emanuel Hospital, where he spent a week for treatment of head and arm injuries. During the attack, the victim's personal belongings were taken, police said.

A Multnomah County grand jury subsequently indicted Wicker on charges of first- and second-degree robbery and second- and third-degree assault.

Anyone who sees him or knows of his whereabouts is asked to call 9-1-1 immediately.
